What’s it about?
The story.
Andy and Terry's treehouse has reached 156 storeys, and this time the chaos has a festive flavour. The new additions and disasters include Christmas-themed mayhem, sneaky snowmen, impossible rooms and the usual pressure from Mr Big Nose to produce a book on time. As with the rest of the series, the plot is really a frame for comedy: every floor invites another ridiculous idea, every attempt at order gets interrupted, and Terry Denton's illustrations make the pages feel full of movement, diagrams, expressions and visual punchlines. This twelfth entry is a strong continuation rather than a starting point, because readers who already understand Andy and Terry's rhythm will get the most from the repetition-with-escalation structure. It is a good seasonal pick for children who like funny illustrated chapter books, but it remains too high-energy and busy for readers looking for a calm Christmas story.

In the classroom
How it works in school.
The anarchic, hugely funny Treehouse series — a legendary reluctant-reader hook and classroom-library staple.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.
Why it lands
Why they love it.
Why kids love it
The specific delight is the Christmas spin — snowmen, festive mayhem, the same impossible architecture wearing fairy lights. A seven-year-old mid-Treehouse phase gets a perfect December read; Andy and Terry trying to finish the book before Christmas hits its target audience like a sleigh.
- Adventure and freedom
- Having a secret base
- Secret world
- Trickery and cleverness
Why parents love it
The Christmas Treehouse — same impossible house, festive overlay. Useful for the December reading slot when a child is mid-series and wants a seasonal entry. The kind of book that survives being read three times across the holidays.
- Shared humour
- Quick to read
- Conversation starter
